Application filed April 18,

To all to 710m it may concern Be it known that I, WILLIAM H. Kann- SICK,a citizen of the UnitedStates, residing at Spokane, in the county ofSpokane and State of Washington, have invented new and usefulImprovements in Wrenches, of which the following is a specification. V

This invention relates to wrenches and has for an object the provisionof a wrench which includes relatively movable jaws after i the manner ofthe usual monkey wrench and which further includes means whereby thewrench may be easilyand quickly converted into a socketed wrench.

Another object of the invention is the provision of a wrench of thischaracter wherein the means for operating the movable jaw may also beemployed for operating the socketed member of the wrench, theconstruction permitting of the use of the wrench in restricted spaces.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation showing the movable jaw inposition and the handle of the wrench rigid.

Figure 2 is a plan view of the same.

Figure 3 is a longitudinal sectional view.

Figure 4. is a transverse section on the line 44 of Figure 1.

Figure 5 is a similar view on the line 55 of Figure 1.

Figure 6 is a detail perspective view of the movable jaw.

Figure 7 is a side elevation showing the wrench arranged as a socketedwrench and the handle disposed at an angle.

Figure 8 is a longitudinal sectional view of the same.

Figure 9 is a transverse section.

Figure 10 is a detail perspective view of the member which carries thesocketed member.

Referring in detail to the drawings, wherein like characters ofreference denote corresponding parts, the wrench is illustrated asincluding a hollow handle 10, one end of which is provided witha crosssectional rectangular portion 11 having one face formed with alongitudinally extending slot 12.

Rotatably mounted within the handle 10 1921. Serial No. 462,135.

in bearings 13, is a shaft 14, which is provided with a square portion15 for the reception of a threaded sleeve 16. the threads of whichextend from the slot 12 provided in the handle. This sleeve ispositioned between one of the bearings 13 and an enter lorly threadednut 17 which is located within one end of the handle.

Removably and slidably mounted upon the rectangular portion 11 of thehandle is a aw 18, the latter being )rovided with an opening 19 ofrectangular shape for the reception of the rectangular portion 11 of thehandle and being provided with threads 20 :For engagement with thethreads of the sleeve 16. By rotating the shaft li'r, the sleeve 16 willbe rotated and the threaded engagement of this sleeve and the jaw 1%W111 impart a longitudinal sliding movement to the latter. The rigid jawof the wrench is indicated at 21 and this aw is provided with aninternally threaded opening 22 which receives a threaded extension 23formed on the handle so that the jaw 23 may be removably secured inposition. This construction provides a wrench which may be used both asa nut or pipe wrench, the shape of the jaw 18 permitting of this latteruse.

In addition, it is the purpose of the invention to provide means wherebythe wrench may he used as a socketed wrench. To accomplish this there isprovided :1 rectangular sleeve 24.- which is designed to receive therectangular portion 11 of the wrench handle, the jaw 18 first beingremoved to permit of the reception of the sleeve 24. This sleeve is of alength substantially co-extensive with the space between the member 13and the jaw 21, which is removed for the purpose of applying the sleeveand replaced to hold the said sleeve in position. The sleeve 24 isprovided with an extension 25, having an opening 26 therein androtatably mounted within this opening is a member 27 having arectangular socket 28 therein. The member 27 is exteriorly threaded forengagement with the threads of the sleeve 16 and for this purpose, thesleeve 24 is provided with an open ing 29. By rotating the shaft 14:,rotary motion may be imparted to the member 27 through its engagementwith the threaded sleeve 16.

Another feature of the wrench is the provision of means whereby it maybe used in restricted places and for this purpose the Specification ofLetters Patent. Pat i a pl 23 1922 shaft 14 is provided with a universaljoint 30, while the hollow handle is formed in sections and hingedtogether at a point ad jacent the universal joint as shown at 31. Theouter end of the shaft 14 is squared as shown at 32 to receive asuitable tool or implement whereby the shaft may be rotated. By movingthe handle upon this hinged portion, the end of the wrench may beinserted in a restricted space, the joint 30 permitting of rotation ofthe shaft 1% when in this position. In order to hold the handle rigidthere is provided an internally threaded sleeve 33 which engages threads34 and 35 formed upon the outer periphery of the handle and when soengaged will bridge the jointed portion of the handle to hold the latter against movement.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is here in reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention what is claimed is A 1. A wrenchembodying a handle, means whereby either a longitudinally movable memberor a rotatable member may be mounted upon the handle and means engageable with either of said members, whereby the same may be operated.

member may be mounted upon the handle" and means including alongitudinally disposed threaded shaftengageable with either said jaw ormember, whereby the same may be operated.

at. A wrench embodying-a handle, means whereby either a longitudinallymovable member or a rotatable member may be mounted upon the handle anda common operating element engageable with either. of said members,whereby the same may be operated. v

5. A wrench comprising a. hollow handle, a cross sectional rectangularouter surface provided at one end thereof for the reception of either amovable jaw or a socketed member, a stationary jaw carried by thehandle, a threaded shaft located within the hollow handle andengagingreither the mov able jaw orv the socketed'member, wherebythesame may be operated.

In testimony-whereof I afiix my signature.

WILLIAM KRUMSICK.
